In first gear, or low gear, an automobile's engine runs about three times as fast as the drive shaft. In second gear, the engine
does not have to run as fast; usually it runs about 1.6 times faster than the drive shaft. Finally, in third, or high gear, the engine runs at the same speed as the drive shaft. Engine speed = 4,100 r.p.m. Transmission in first gear Drive-shaft speed (to nearest r.p.m.) = a) 1367
b) 12,300
c) 6560
